Message from the General Chair

Welcome to the 1st Conference of the Asia-Pacific Chapter of the Association for ComputationalLinguistics and the 10th International Joint Conference on Natural Language Processing (AACL-IJCNL-2020) virtually hosted by Soochow University, China. I am honored to be the General Chair of the firstconference of AACL and am excited to welcome you to the event.

Research in NLP in the Asia-Pacific region is rapidly growing. This is evident from the increasingnumber of paper submissions and participants in recent NLP conferences worldwide. Many innovativeNLP theory and applications are presented in these events. To better share NLP innovations in the region,the Association for Computational Linguistics (ACL) established the Asia-Pacific Chapter of (AACL)in 2018. AACL provides a regional focus for ACL members in Asia-Pacific region to promote and tofacilitate cooperation and information exchange among related scientific and professional societies andindividuals in the region. This is the first bi-annual meeting of the Chapter and is jointly organizedwith the 10th International Joint Conference on Natural Language Processing (IJCNLP), which is thebi-annual conference of the Asia Federation of Natural Language Processing (AFNL), a well-establishedassociation sharing the same missions as AACL. There is a saying “1+1 > 2” in China and this jointconference truly reflects that. AACL-IJCNLP-2020 is just a beginning, AACL will initiate morecollaborations with AFNLP and other regional associations in the future so as to let the world appreciatemore the work of the NLP communities in Asia-Pacific.

Soochow is a scenic and historic Chinese city. The city’s canals, stone bridges, pagodas and meticulouslydesigned gardens have contributed to its status as one of the top tourist attractions in China. Noticeably,the Classical Gardens of Soochow were added to the list of the UNESCO World Heritage Sites in 1997and 2000. Soochow is often dubbed the “Venice of the East” or "Venice of China". These attractionswould have added another flavor to the AACL-IJCNLP-2020 blending it a cultural and technical event.Several cultural tours and social events were originally planned. They would have been eye-openingto the participants. However, a face-to-face physical conference gave way to the COVID-19 pandemic.After a long period of observation since the beginning of the year, due to the growing severity of thepandemic worldwide, the local organizing committee recommended to organize AACL-IJCNL-2020virtually in September. This was a difficult decision; but for safety reason, the team and I believed thiswas the right choice. Organization of a virtual conference was unconventional. It created a new set ofchallenging problems unfamiliar to the team. Fortunately, ACL2020 took place before AACL-IJCNLP-2020 and we learned much from their experience.

The program co-chairs Kevin Knight and Hua Wu did an excellent job in putting together a veryinteresting program with 92 papers from submissions worldwide. The program also includes two starkeynote speakers, Percy Liang, Stanford University, and Song-Chun Zhu, Peking University, TsinghuaUniversity, and UCLA, to share with us their insights in “semantic parsing” and “explainable AI”respectively. These are hot topics both in pure and applied research. Selecting the papers from nearly400 submissions was itself a difficult task but it was compounded by the complication in the design ofthe virtual program. Kevin and Hua had to take into account of the different time zones of the authorsand audience and was rather tricky. Nevertheless, after many iterations, they came up with the currentexciting program.

The conference is accompanied by 7 workshops and 6 tutorials. We participated in the joint selectionprocesses with other ACL related conferences. The workshop co-chairs, Wei Gao and Lu Wang as well asthe tutorial co-chairs Timothy Baldwin and Fei Xia did a wonderful job to select these very educationaland trendy topics. In addition, despite the busy program schedule, with the dedication of the studentworkshop co-chairs, Lun-Wei Ku and Vincent Ng, we also put up a student research workshop; and withthe dedication of the demo co-chairs, Douwe Kiela and Derek Wong, we accepted 7 system projects

iv

out of 15 for demonstration. As a part of ACL’s Diversity and Inclusion (D&I) initiative, we introducedthe Widening NLP (WiNLP) session in the first day of the conference. Xiangyu Duan and TirthankarGhosal, the D&I co-chairs, were very creative in organizing the session and other virtual D&I gatheringevents.

The publication co-chairs Steve DeNeefe and Satoshi Sekine worked diligently and carefully to collectthe accepted papers for compilation of the electronic proceedings. Following the ACL guidelines, thepapers are also included in the ACL Anthology. Since AACL-IJCNLP-2020 is a virtual conference,we decided not to compile a physical handbook. As such, information about the conference is madeavailable online.

The local organization committee was chaired by Min Zhang. As usual, LOC is the committee whichdoes all the ‘dirty’ jobs, ie hands-on work. Under Min’s leadership, LOC did a fantastic job in lookingafter all the details in local arrangement. Organizing a virtual conference was new to Min and the LOC.They put extra time and effort to ensure every single organization details were properly arranged. I alsoappreciated the frustration of the LOC at the beginning. They booked all the venues while the spreadingof the COVID19 pandemic showed no sign of slowing down. We waited until September before wedecided not to go for the face-to-face option, which left us with rather little ime to prepare for the virtualconference. I am glad that we finally make it.

Working closely with the LOC, the remote presentation co-chairs, Nanyun Peng, Zhongqing Wang andMuyun Yang liaised with the program committee, demonstration committee, workshop committee, andtutorial committee to ensure presentations would be done smoothly. The webmaster, Junhui Li, wasalso part of the LOC, to ensure information related to the conference was timely distributed. MirellaLapata, Haizhou Li and Qun Liu, the publicity co-chairs, made use of this conference information forinternational publicity through different channels, eg ACL, SIGIR, AAAI etc communities, and media.Eg. Instagram, Twitter, Facebook, Email, Wechat, etc.

Last but not the least, I would like to thank Priscilla Rasmussen, business manager of ACL HQ, for herinvaluable advice throughout the AACL-IJCNLP-2020 project. She is definitely the most knowledgeableperson in ACL event matters. And I am grateful to Haifeng Wang, President of AACL, and ChengqingZong, President of AFNLP, for their trust. Undoubtedly, without their unfailing support, AACL-IJCNLP-2020 would not be possible. Also, thanks are due to Baidu and Huawei, the Diamond level sponsor, aswell as Bloomberg and Grammarly for their generosity in supporting our D&I drive.

Enjoy AACL-IJCNLP-2020!

Message from the Program Chairs

Greetings, and welcome to AACL-IJCNLP 2020, the First Conference of the Asia-Pacific Chapter ofthe Association for Computational Linguistics (AACL) and the Tenth International Joint Conference onNatural Language Processing (IJCNLP)!

The Asia-Pacific Chapter of AACL is the newest chapter of AACL, and its first conference was heldin 2020. The AACL-IJCNLP 2020 conference received 392 submissions to the main conference. Weaccepted 106 papers (73 long, 33 short), for an overall 28.3% acceptance rate. Submissions came fromall over the world. Of the 106 accepted papers, 53 were from the Asia-Pacific region (28 from China, 10from Japan, 7 from India, 3 from Taiwan, 2 from Australia, 2 from South Korea, and 1 from Indonesia),31 from the Americas (27 from the USA, 3 from Canada, 1 from Brazil), and 22 from Europe and theMiddle East (9 from the UK, 5 from Germany, 2 from France, 2 from Israel, 1 from the Netherlands, 1from Italy, 1 from Denmark, and 1 from Belgium). 14 accepted papers were withdrawn by the authors,due to simultaneous submission to other conferences, resulting in a total of 92 papers presented at themain conference of AACL-IJCNLP 2020.

Like most conferences in 2020, AACL was a virtual one. Conference organizers opted for a real-timemeeting, with papers grouped into topical sessions as done previously for in-person conferences. Authorsfurther pre-recorded talks for convenient, off-schedule viewing.

We had two keynote addresses this year, one by Percy Liang of Stanford University, and one by Song-Chun Zhu of Peking University, Tsinghua University, and UCLA. Many thanks to Professors Liang andZhu for exciting the AACL-IJCNLP participants with their sweeping talks!

For the main conference, 46 Area Chairs oversaw 392 submissions to 18 tracks. We would like to thankthe Area Chairs and reviewers for their hard work. In addition, thanks to Rich Gerber of SoftConf for hisalways-timely help and Natalie Schluter for sharing the ACL 2020 paper-review matching tool with us.We would also like to thank the General, Local, and Publication Chairs for guidance and assistance increating the main conference program. Finally, many thanks to the authors who carried out the researchand submitted their work to AACL-IJCNLP 2020. We hope that the new AACL will continue to be avibrant place to exchange research and ideas!
